Information in this document applies to any platform.

GOAL
The goal of this document is to provide guidance on How to Identify and Diagnose Fan Failures on Sun SPARC
Enterprise T5120 / T5140 / T5220 / T5240 / T5440 and Netra T5220 / T5440 servers.
Fan failures are typically made known to user by reporting a /SYS/FAN_FAULT LED indicator being ON.

SOLUTION
Determine which of the fan modules are faulty or failed, keeping in mind that there are usually multiple fan
modules within a given system.
Using the machine's service processor to perform diagnostics and fan module identification, the following output
will be seen from issuing ILOM or ALOM commands:
*Note: The Service Processors of T5XX family of servers are by default configured to operate under an ILOM shell,
by default.You can create an ALOM compatibility shell if you prefer to use commands that resemble ALOM CMT
commands to administer your server.
Please see the following article for more information on How to Configure the ILOM for ALOM Compatibility Shell on
T5120/T5220/T5140/T5240/T5440/T6320/T6340/Netra T5220/Netra T5440/Netra T6340 (Doc ID 1543116.1)
Examples:
For ILOM commands:
